20110017636 | Systems and Methods for Producing a Crude Product - A process for hydroprocessing heavy oil feedstock is disclosed. The process operates in once-through mode, employing a plurality of contacting zones and at least a separation zone to convert at least a portion of the heavy oil feedstock to lower boiling hydrocarbons, forming upgraded products. The contacting zones operate under hydrocracking conditions, employing a slurry catalyst for upgrading the heavy oil feedstock. At least an additive material selected from inhibitor additives, anti-foam agents, stabilizers, metal scavengers, metal contaminant removers, metal passivators, and sacrificial materials, in an amount of less than 1 wt. % of the heavy oil feedstock, is added to at least one of the contacting zones. In one embodiment, the additive material is an anti-foam agent. In another embodiment, the additive material is a sacrificial material for trapping heavy metals in the heavy oil feed and/or deposited coke, thus prolonging the life of the slurry catalyst. | 01-27-2011 |
20110049010 | Systems and Methods for Hydroprocessing a Heavy Oil Feedstock - Systems and methods for hydroprocessing a heavy oil feedstock are disclosed. The system employs a plurality of contacting zones and at least one separation zone, wherein a solvating hydrocarbon having a normal boiling point less than 538° C. (1000° F.) is employed. In the system, a mixture of heavy oil feedstock and solvating hydrocarbon is provided to a contact zone along with a slurry catalyst feed in a hydrocarbon diluent. The contacting zone operates at a temperature and pressure near the critical temperature and pressure of the heavy oil and solvating hydrocarbon mixture to convert at least a portion of the heavy oil feedstock to lower boiling hydrocarbons, forming upgraded products. | 03-03-2011 |
20120172200 | HYDROPROCESSING CATALYSTS AND METHODS FOR MAKING THEREOF - A single metal slurry catalyst for the upgrade of heavy oil feedstock is provided. The slurry catalyst is prepared by sulfiding a Primary metal precursor, then mixing the sulfided metal precursor with a hydrocarbon diluent to form the slurry catalyst. The single-metal slurry catalyst has the formula (M | 07-05-2012 |
20120172203 | HYDROPROCESSING CATALYSTS AND METHODS FOR MAKING THEREOF - An improved process for preparing a slurry catalyst for the upgrade of heavy oil feedstock is provided. In the process, high shear mixing is employed to generate an emulsion containing droplets of metal precursor in oil with droplet sizes ranging from 0.1 to 300 μm. The emulsion is subsequently sulfided with a sulfiding agent, or in-situ in a heavy oil feedstock to form a slurry catalyst. The in-situ sulfidation in heavy oil is under sufficient condition for the heavy oil feedstock to generate the sulfiding source needed for the sulfidation. | 07-05-2012 |
20130197637 | METHOD FOR MAKING NOVEL COMPOSITIONS CAPABLE OF POST FABRICATION MODIFICATION - The invention relates to a novel method for preparing materials whose properties can be manipulated after fabrication. In this process, a base material is created in a manner that provides spaces or voids which can then be filled with a modifying composition. The method is particularly useful in the manufacture of light adjustable optical elements such as intraocular lenses. | 08-01-2013 |
